Just got into the game pretty late but addicted to it right away.

Got a question about building a deck. When building a new deck like the baratheons and I have duplicate king robs from the core set if I add another rob from a chapter or expansion pack will it be counted as another duplicate or a different character? Thanks

If they have the same title, they count as the same character. So you can only have up to 3 cards with "Robert Baratheon" at the top, regardless of what versions they are.

And since this is the deckbuilding forum, I'll point out that it's pretty rare to see decks that use multiple versions of the same unique card. You're welcome to experiment, but it's usually better to figure out which version suits your deck best and just use that one.

You can't marshalling 2 unique character with the same name. If you have one in play the second "Rob" will be a duplicate of the first.

Thanks

So no matter what set a character comes form you can only have 3 with the same name?

That's what the man said - and what the rules say.
